Beginning Training

The night passed without incident...

"Is this the power of chakra?"

As a brilliant ray of sunlight fell across Yun Xi's handsome face, he finished his night of training.

He slowly stood up.

After a night of training, Yun Xi discovered...

Not only had his body clearly grown stronger, but he had also noticed an astonishing change!

The amount of chakra in his body had more than doubled!

Before Yun Xi had crossed over, this body had contained only a tiny amount of chakra.

But after just one night of training...

Yun Xi now had enough chakra to reach Genin level!

One night.

From an ordinary person to a Genin!

Not even Yun Xi himself...

Or even extraordinarily gifted young prodigies like Uchiha Itachi and Sasuke could manage that!

"This system really is powerful..."

Yun Xi had once thought the system he'd obtained was nothing but a piece of junk.

But...

It seemed that wasn't the case.

At the very least, Yun Xi now had the ability to protect himself!

With Genin-level chakra and a single-Tomoe Sharingan...

He should have no trouble dealing with an ordinary Genin!

"Next, I'll train in the Fire Release Ninjutsu Uchiha Itachi gave me!"

Perhaps it was the effect of the chakra in his body, or perhaps something else.

Despite training all night, Yun Xi didn't feel tired or exhausted. After washing up, he had no intention of going to rest.

Instead, he slowly picked up the Fire Release Ninjutsu scroll Uchiha Itachi had given him.

Then he headed straight for the forest behind Konoha...

Training in ninjutsu was different from training in chakra.

The latter only required a quiet place, while training in ninjutsu required a large open space and plenty of practice and experimentation.

There wasn't a suitable place to train at Yun Xi's house.

And he didn't want to burn it down...

So the mountain was the best choice!

With chakra boosting him, Yun Xi made the journey in just over ten minutes, though it would normally have taken half an hour.

Even after cutting the travel time in half, he didn't feel tired!

He casually wiped the sweat from his forehead with his sleeve, then unrolled the Fire Release Ninjutsu training scroll Uchiha Itachi had given him.

The scroll didn't contain much—only five techniques.

But they were very well suited to Yun Xi!

"I'll start with this one: Fire Style: Phoenix Sage Fire Technique!"

Once he'd chosen his target, Yun Xi studied Uchiha Itachi's training notes while repeatedly practicing the Hand Seals.

Though Fire Style: Phoenix Sage Fire Technique was only a C-rank Fire Style Ninjutsu...

It was very effective in actual combat.

Its range was wide, and its power was not to be underestimated.

The main reason Yun Xi chose this technique was that it didn't require much chakra.

A simple technique that conserved chakra and had a wide range of uses was sure to be the best choice for him!

"Fire Style!"

"Phoenix Sage Fire Technique!"

After practicing for about an hour, Yun Xi finally tried to use the technique...

But the result...

Surprised him.

After Yun Xi completed the Hand Seals and gathered chakra in his mouth...

He blew hard!

Only a dozen or so flames appeared, each about the size of a lighter's flame...

Never mind their ability to cause damage.

After seeing them, Yun Xi even wondered if they'd be enough to cook a meal...

"Damn it!"

Seeing the Fire Style Ninjutsu he'd just performed, Yun Xi's face turned awkward. He muttered, "What the hell kind of Phoenix Sage Fire Technique is this?"

The Phoenix Sage Fire Technique...

Was one of the most famous Fire Style Ninjutsu in Naruto.

Not only had Uchiha Sasuke used it extensively early in the story, but powerful Kage-level shinobi such as Uchiha Itachi, Uchiha Shisui, and Uchiha Obito could all use it too.

It could be considered an essential technique of the Uchiha Clan.

So Yun Xi was quite familiar with it.

As he remembered it, the flames released by the Phoenix Sage Fire Technique scattered in all directions, like the seeds of the impatiens flower bursting away when touched. The flames shot from the user's mouth to attack their enemies.

And once the technique was mastered, the user could control all the flames with chakra, leaving their enemies unable to dodge.

It was not only spectacular to watch, but also incredibly powerful!

But...

The Phoenix Sage Fire Technique Yun Xi had performed fell a little short...

Never mind whether his chakra could control the flames he'd released.

They couldn't even inflict basic damage...

"That can't be right!"

As the flames he'd released gradually died out, Yun Xi began to doubt himself a little!

He checked Uchiha Itachi's Fire Style training methods and the Fire Style training insights the system had rewarded him with again, but he couldn't find any obvious mistakes in how he'd performed the technique.

And Yun Xi wasn't an ordinary person!

When he trained in Fire Style Ninjutsu, the system had already strengthened his body.

First, he'd received the Uchiha Clan bloodline enhancement.

Then he'd been strengthened with that special Ichiraku Ramen!

Before trying the technique, Yun Xi hadn't expected much.

But he'd never imagined his first attempt at this Fire Style Ninjutsu would turn out like that...

"System, you didn't forget to give me the reward, did you?"

Suddenly, Yun Xi realized something.

He immediately questioned the system in an extremely serious tone.

But...

The system didn't offer any explanation...

A dark line appeared on Yun Xi's face...

"Your chakra is too low..."

Just as Yun Xi was beginning to doubt himself, a cold voice reached his ears again.

"Who?"

Hearing that, Yun Xi quickly turned around.

He saw Uchiha Itachi, with a cool-looking little boy beside him.

"Your attempt at the Phoenix Sage Fire Technique had no obvious mistakes, and your timing was precise, but you didn't have enough chakra to form the technique properly."

As Uchiha Itachi walked toward Yun Xi, leading the little boy by the hand, he explained why Yun Xi's Phoenix Sage Fire Technique had failed.

Then Uchiha Itachi gestured for the little boy beside him to sit down before walking over to Yun Xi.

As he quickly formed the Hand Seals, he said, "Watch carefully. If you don't have enough chakra, you can reduce the number of flames to increase the power of the Phoenix Sage Fire Technique!"

With that, Uchiha Itachi released a complete Phoenix Sage Fire Technique from his mouth!

Though this Fire Style: Phoenix Sage Fire Technique was different from the usual version.

It produced only one flame...

But...

Compared to the Fire Style: Phoenix Sage Fire Technique in the original story, the one Uchiha Itachi had just performed was clearly much more powerful!
